控释颗粒配方:甲氧萘丙酸450mg,氢化蓖麻油171mg,乙基纤维素54mg; 将以上两种颗粒混匀,压片制得。 2、长效氯化钾片 取处方量氯化钾结晶悬浮于熔融的鲸蜡醇、氢化蓖麻油和硬脂酸中,搅拌至将近凝固时通过20目筛制成颗粒,颗粒再与明胶液拌后通过10目筛,制粒。室温干燥后加润滑剂压成片芯,最后包糖衣即得。3、N一(a羟乙基)烟碱酰硝酸酯骨架片 取氢化蓖麻油90g,用微粉磨分散成直径1.5µm的微粒,即刻与羟丙基纤维素8g混合,混合物用10%羟丙基纤维素20g与水43g 混合制粒,50℃干燥制得颗粒A;取上述混合物A2.5g,加入主药7.5g,制成颗粒B;取乳糖5.9g,微晶纤维素3g,硬脂酸镁0.1g和主药1g混合制成颗粒C;将颗粒A、B、C混合压片即得。 4、缓释包衣层材料 特定药品需要通过包衣层来达到缓释效果,氢化蓖麻油是常用的缓释材料之一,一般用量为衣层总重量的5.0%-20.0%。 B、用作润滑剂 氢化蓖麻油可用作片剂的润滑剂,其润滑作用虽然不及硬脂酸镁,但对少数在压片过程中产生粘冲的片剂,氢化蓖麻油是最好的选择,比如硫酸氢氯吡格雷片就需要采用氢化蓖麻油作为润滑剂。 实际大多数极性较强药物(亲水性较强药物)、以及压片过程中容易造成花斑的药物,都可选用氢化蓖麻油作为润滑剂,既可起到润滑作

921WATER DETERMINATION水分测定 Many Pharmacopeial articles either are hydrates or contain water in adsorbed form. As a result, the determination of the water content is important in demonstrating compliance with the Pharmacopeial standards. Generally one of the methods given below is called for in the individual monograph, depending upon the nature of the article. In rare cases, a choice is allowed between two methods. When the article contains water of hydration, the Method I (Titrimetric), the Method II (Azeotropic), or the Method III (Gravimetric) is employed, as directed in the individual monograph, and the requirement is given under the heading Water. 很多药典物品要么是水合物,要么含有处于吸附状态的水。因此,测定水分含量对于证实与药典标准的符合性是很重要的。通常,在具体的各论中会根据该物品的性质,要求使用下面若干方法中的一个。偶尔,会允许在2个方法中任选一个。当该物品含有水合状态的水,按照具体各论中的规定,使用方法I(滴定测量法)、方法II(恒沸测量法)、或方法III(重量分析法),这个要求在标题水分项下给出。 The heading Loss on drying (see Loss on Drying 731) is used in those cases where the loss sustained on heating may be not entirely water. 在加热时的持续失重可能不全是水分的情况下,使用标题干燥失重(见干燥失重<731>)。 METHOD I (TITRIMETRIC) 方法I(滴定测量法) Determine the water by Method Ia, unless otherwise specified in the individual monograph. 除非具体各论中另有规定,使用方法Ia来测定水分。 Method Ia (Direct Titration) 方法Ia(直接滴定) Principle— The titrimetric determination of water is based upon the quantitative reaction of water with an anhydrous solution of sulfur dioxide and iodine in the presence of a buffer that reacts with hydrogen ions. 原理:水分的滴定法检测是基于水与二氧化硫的无水溶液以及存在于缓冲液中与氢离子反应的碘之间的定量反应。 In the original titrimetric solution, known as Karl Fischer Reagent, the sulfur dioxide and iodine are dissolved in pyridine and methanol. The test specimen may be titrated with the Reagent directly, or the analysis may be carried out by a residual titration procedure. The stoichiometry of the reaction

蓖麻油及其衍生物在涂料中的应用汇总

蓖麻油及其衍生物在涂料中的应用 0 引言 20 世纪 70 年代 , 由于石油资源短缺 , 可再生资源曾一度受到很大的重视[1] 。 80 年代后期由于环保问题以天然产物及其衍生物等可再生资源为基础的聚合物重新获得了关注 [2] 。植物油来源广泛且可再生 , 以植物油为原料制备的涂料成本低且有利于保护环境。蓖麻油就是其中的 , 它是惟一以含羟基酸为主的商业油脂 [3] 。与其他植物油相比 , 其特点在于它的高羟值和高酰值 , 另外它几乎不溶于石油类溶剂 , 但是可以溶于乙醇。蓖麻油的主要产地在印度、巴西、中国以及前苏联 , 我国的年产量居世界第三位 , 产于全国各地 , 其中以吉林省为最多。我国生长的蓖麻属于温带一年生大粒蓖麻 , 籽中含油量高达 50 % 以上 , 比印度和巴西的热带蓖麻籽含油量要高出 5% ~ 10 % 。故现今世界上不少蓖麻油开发利用比较先进的国家 ( 如日本等 ), 多从我国进口蓖麻籽进行深加工及应用 [4] 。 1 蓖麻油的组成与性质 蓖麻油属于不干性油 , 它的主要成分为高级脂肪酸的甘油三酸酯。其皂化值在180 mg KOH/ g 以上 , 碘价为 82 ~ 90 mg I 2 /g, 羟值为 155 mg KOH/ g 以上。表 1 列出了蓖麻油脂肪酸的主要成分 , 其中蓖麻油酸 ( 化学名为 12 - 羟基 -9- 十八烯酸 ) 在天然植物油中羟值最高。 蓖麻油酸的成分为甘油三酸酯 , 其分子并不排列在同一平面上 , 所以其双键聚合之后 , 会形成立体网状结构 [6] 。如图 1 所示 , 蓖麻油酸分子结构中含有羟基 , 易形成氢键而产生缔合 , 造成其黏度比一般植物油大 8 ~ 10 倍[7] , 另外它的相对密度与极性均较其他植物油大。同时其支链上还含有羟基和不饱和双键 , 因此可以发生水解、酯化、加成、氧化、裂化、环氧化、酰胺化、脱水等反应。在些反应中 , 酯化反应以及脱水反应在涂料工业上得到了很大的应用 [8] 。这一方面决定了蓖麻油开发利用的多种途径 , 另一方面对蓖麻油的精炼工艺也提出了高的要求 [9] 。 表1 蓖麻油中脂肪酸的含量( 质量分数) [5] %
